According to the doc, BPXWDYN has additional keywords available vs TSO ALLOCATE. One of these is GDGNT, which has the following description: "The S99GDGNT flag is set in the S99FLAG1 field. For information about this flag, see z/OS MVS Programming: Authorized Assembler Services Guide."
The Assem Serv Guide contains the following description for the S99GDGNT flag: "When the bit is on, the system is to use a LOCATE to determine the relative generation number based on the most recent catalog information. The relative generation number will reflect GDG data sets created or deleted by other jobs in a multitasking environment. When the bit is off, the system is to determine the relative generation number based on the catalog information that was available the first time the GDG was referenced during the job or TSO/E session. The relative generation number will reflect only those GDG data sets created or deleted by this job."
